A stiffness tester is an instrument that is used to measure the stiffness or flexibility of materials, such as fabrics, plastics, paper, and cardboard. Stiffness is a physical property that describes a material's resistance to bending or deformation under an applied force. Stiffness testers are commonly used in industries such as textiles, paper, and packaging to ensure that products meet specific stiffness requirements for their intended applications.
